To all whom 'it may concern:

Be it known that. I, WILLIAM A. JorLrN, citizen of the United States, residing at Lawrence, county of Essex, and State of Massachusetts, have invented a certain new and useful Improvement in Machines for Lining Boxes, of which the following is a specification, reference being had therein to the accompanying drawings.

In putting up package goods in boxes, either when the goods are packaged in advance, or when they are put up by the salesman by order at the counter, as for instance, cereals, candy, sugar or the like, it is very generally the custom to insert. a paper lining into the box beforethe goods are introduced into the'box. Heretofore so far as I am aware, linings have always been inserted by hand.

The object of my invention is to produce mechanism whereby the boxes may be lined more` rapidly than can be done by hand.

The invention will be fully understood from ihe following description taken in con- .nertiou with the accompanying drawings,

and the novel features are pointed out and clearly defined in the claims at the close of the specification.

In the drawings,-Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a front elevation. Figs. 3, 4 and 5 are detail perspectivev views, partly in section, showing successive stages of the folding mechanism in the operation of folding and inserting the lining into the box. Fig. 6 is a top plan view of a portionof the belt and of the reciprocable slide rod and angle plates which forni the pocket for the carton during the lining operation and showing the latch for holding the carton when the plun `ger iswithdrawn. ,Fig T is a detail view of the latch turned one side to allow the transverse movement of a carton across the belt into position under the plunger. is a sectional detail showing the valve and its operating mechanism for introduction of compressed air through the plunger' block to prevent the lining from sticking to the plunger block when it. is withdrawn from the carton after the lining has been inserted.

Referring to the drawings,-in the illustration of the invention shown the boxes are represented by what are termed cartons and are represented as being brought. adjacent to the proper place for receiving the lining by rig. s-

means of a wide traveling belt and are moved by other mechanism successively one at a time in a transverse direction to another.l

position on the belt to receive the lining.

1 represents the traveling belt and 2 the cartons. The width of the belt is about twice the thickness of the cartons for the reason that will be hereinafter explained.

Adjustably secured to the two standards 3, 4, respectively, are the brackets 5, 6, to which are secured the two tables or shelves 7, 8, which are spaced apart a suihcient distance to allow for the passage of the plunger block 9 which carries the lining sheet down into the carton, the lining sheet 10 being placed upon the two tables 7, 8, so as to bridge the space between them to be engaged by the plunger in its descent.

Fixedly, but. adjustably, secured to a depending arm 11 of the table 8 is'an angle plate having two arms 12, 13, at right angles to each other, the arm ,13 extending crosswise of the upper run of the belt 1, just above it and extending crosswise for about half of the width of the belt.

Mounted in the4 guide support 14 is a horizontally reciprocable slide rod 15 which extends forward beneath the upper run of the belt and to some distance in front of the same, having atits forward end an up-l turned angle arm 1G to which is secured an shaped angle plate having an intermediate portion 17 which lies in a vertical plane parallel with the belt and at one end a bent arm 18 which extends transversely of the belt, about half way across the belt on the opposite edge from the arm 13 and parallel with it, and at the other end an arm 19 which extends also at right angles with the body portion 17 of the angle plate parallel with the arm 18, but in the opposite direction. The'boxes are placed on that side of the upper face of the belt which in the travel of the belt will bring the box up against the arm 18 when the plunger 15 is in its most retracted position.

rlhe slide or plunger rod 15 is connected with suitable mechanism whereby the said rod, at proper times, may be made to reciprocate transversely with relation to the belt. The box on the belt is brought up against the arm 18, and alongside of the upright intermediate portion of the angle plate 17. lVhen the plunger rod is moved to the right as shown in Fig. 1, the plate 17 process of inserting the lining. The arm 19 will extend transversely of that portion of the belt on which the cartons or boxes arc cariied so as to stop the advance of any oncoming boxes until the movable angle plate 17 is retracted by the plunger rod 15.

Slidable in ways in the standards 3, 4, is a cross-head 20 from which is suspended rigidly a block 9 of the rightsize and shape to loosely fit inside of the box which is to be lined. This block is hung so as to be centered over the open space between the tables 7 and 8 through which the block is to pass in its descent and also directly over the carton or box when it is positioned as previously described to receive the lining. The cross-head 20 is connected with suitable mechanism for causing it to be raised and lowered at the proper time. r1`he means shown in the drawings for operating the cross-head are as follows: Fulcrumed at one end on the stud 21 having bearings in a bracket 22 is a rocking lever 23, the forward end of the said rocking lever 23 being connected by a connecting rod 24 to the crosshead20 at 25.

Mounted on a rotary shaft 26 isa cam 27, the shaft 26 being driven in any suitable way. rThe means shown consist of a driving wheel 28 on shaft 29 carrying pinion 30 which engages withgear wheel 31 on the shaft 26. Any suitable driving mechanism, however, may be employed. Carried on the rocking lever 23 is a roll 32 which engages with the cani 27, whereby the rocking lever is given the proper movement to raise and lowerthe cross-head 20 and thereby the block 21.

The mechanism shown for actuating the plunger rod 15 previously. described is as follows: Fulcruined on the stud 2l is a rocking lever 33 to the forward end of which is connected the connecting rod 34, the lower end of which is pivotally connected to a lever 35 which is keyed to or otherwise inade fast to the rockshaft 36. Rigidly connected with the roekshaft 3G is also a lever 37 forked at its lower end to engage a stud 38 projecting from the horizontal plunger rod 15. Mounted on shaft 26 is a cani 39 which engages a roll 40 carried on the side of the rocking lever 33 whereby the rocking lever 33 is actuated to raise the connecting rod 34 and thereby, through the arm 35 and shaft 36, to turn the forked lever 37 and move the plunger rod 15 to the left, viewing the machine as in Fig. 1, and thereby move the angle plate 17 away from the carton. 1n

connecting rod 34 and thereby, through the connecting mechanism, cause the plunger rod 15 to be moved to the right from the position shown in Fig. 1 viewed fiom the 'same side, to move the angle plate 17 in the direction to push the box in fi'ont of it up against the arm 11 into position to receive the lining.

Hinged to the upper side of the table 8 at its edge on a hinge 42 is a plate or leaf 43 having a portion 44 which extends part way over the space between the two tables, the said plate normally lying fiat upon the upper s'ide of the table.

Adj ustably secured to the plate 43 are two angle plates 45 with flanges 46 spaced apart from each other enough to embrace the plunger block 9 when it descends. The plate 45 may be adjustably secured to the plate 43 by clamp-screws 47 passing through slots in the plate 45 into the plate 43. The purpose of making them adjustable is to allow for plunger blocks of different widths.

The tables 7, 8, are supported by the brackets 5, 6, respectively, by means of tongues 90 which project from the sides of the tables and engage in grooves 91 in the sides of the lugs 92 on the brackets, said tongues being slidable in said grooves for the purpose of adjusting the two tables 7 8, toward and from each other, thereby enabling the distance between the folding plates 43 and 48 to be varied to accommodate blocks of diderent thickness.

Hinged to the edge of the table 7 by a hinge 49 is a plate 48 having a projecting portion 50 which extends part way across the space between the tables 7, 8. toward the projecting portion 44 of the platt 43. Preferably this plate 48 is formed with a slot 51 to make the plate as light in weight as possible.

Secured to the depending arms of the table 8 are two guide plates 52, one on each side of the table, extending parallel with each other about two-thirds of the way across the space between the two tables, and spaced apart from each other sufficiently to allow the passage of the block 9 between them.

Securedlto the depending portion of the table 7 are two curved guides 53, one on each side of the table, extending part way across the space between the two tables lapping .past and outside of the guide plates 52.

When a box to be lined is brought into proper position by the forward movement of the plunger rod 15 inclosed inthe rectangular pocket previously described formed by the arms 17, 18, 11, 13, a sheet 10 of the liningpaper being placed upon the two tables 7, 8, bridging the space between them, and lapping over onto the two tables, the machine is operated to causethe block 9 to descend which, in the course of its descent, strikes the upper surface of the spread out sheet 10 of lining paper where it covers the inward projections 44 and 50 of the hinged plates 43, 48, and as it continues its descent, the pressure upon the inwardly extending portions 44 and 50 of the hinged plates 43, .48, turns the portions 44 and 50 down and turns the plates 48, 48, upon their hinges, bringing then 4up into ay vertical position as shown in Fig. 4, thereby folding the lining sheet up ovei the lower end of the block 9 and turning it up against the front and hack sides of the block, and the wings 46 will turn the laterally extending portions 61 of the lining sheet around against the other two sides or edges of the block 9 as shown in Fig. 4. As the block further descends, the plates 52 will engage and fold over the lower front corners and crease the bottomseam of the paper as shown in dotted lines 54 inA Fig. 4. The further .descent of the block l brings the laterally extending portions 55 of the lining which was turned up by the plate 48 into engagement with the curved guides 58, thereby folding the extended portions 55 of the lining up against the outer side of the guide plates 52 so that the portions 55 will lie flat between the guides 52 and 53, but the continued descent of the block will carry it below the guides 52 so that then the wings 55 will lie against the wings 61 of the lining.

Pivoted to the depending arms of the tables 7, 8, are two pairs of levers 56 in each pair of which is journaled a presser roller 57 which is held by springs 58 with yielding pressure against the folded lining of the block as the block descends in order to smooth the lining upon the block before the block enters the box 2. The block 9 sho'ld be enough smaller than the box so that the block with the lining folded thereon will easily enter the box. The downward movement of the block 9 is so adjusted that the block will descend just far enough to Carr;7 the lining to the bottom of the box.

The cam 27 lifts the rocking lever 23, and thereby the block 9, at the proper period in its rotation, and when the high point ofthe cam has passed ,off the roller, the mere weight of the block 9 is sufficient to cause the descent of the block. Any proper means may be used, however, for elevating and depressing the block at the proper time.

The brackets 5, 6,A which support the tables 7, 8, are adjustable vertically by means of the clampscrews 59 which pass through elongated slots 60 in the brackets to provide for difference in th heights of the cartons.

As the belt 1 is constantly traveling inthe direction indicated by the arrow in Fig. 6

-even during the time that the lining is being inserted into the carton, it tends to drag the carton, which is being lined, against the arm 18 as shown in Fig. 6, and when the angle plate 17, 18, is moved back after the lining has been inserted, on account of the pressure of the carton against the arm 18, there is a tendency for the carton to be dragged back to some extent and, therefore, to drag it out of the proper alinementf with the course which it should take in being carried away by the belt after the arm 18 has entirely withdrawn. For this reason, it' is desirable Ato provide some means for restraining the carton from being dragged back with the angle plate 18. The means which I have provided are as follows: A block 62 is -pivotedy at 63 to a bracket 85 which is secured to the frame. Said block is so pivoted as to be permitted a rocking movement-on a vertical axis. Fast to one side of the block 62 is a plate 64 terminating in a bent latch which extends through a slot 84, shown in dot-ted lines in Fig. 1, said slot extending laterally through the arm 18 of the angle plate and extending for a short distance into the edge of the plate 17. The latch 65 engages the corner of the carton 2 when in its position under the plunger. When the plate 17 is retracted, the slot in the plates 17, 18, allows the plate to move back without interfering with the latch 65, and the pressure of the latch 65 on the carton will prevent the carton from being dragged back with the angle plate. Securedto the opposite side of the block 62 fromthe latch plate 64 is a spring 66, the forward portioi of which bears against a stud 67. When the angle plate 1i' moves forward with a carton to bring it under the plunger, the side of the carton will engage the curved heel of the catch. 65 and thus rock the block 62 on its pivot and turn the catch plate 65, as shown in Fig. 7, to allow the carton to ride past it. lVhenl the block is thus turned, the spring 66 is flexed, and

after the carton has been carried forward its full movement into position under-,the plunger, the spring 66 will turn the block 62 on its pivot and thereby bring the catch into engagement with a corner of the carton as shown in Fig. 6.

It is found that when the plunger block 9 is raised out of the carton after having inserted the lining, the lining has a tendency to cling to the plunger block and to be partially pulled out or disarranged. Suitable means should be provided to overcome this tendency. The means which I have provided are to inject into the carton down through the plunger block compressed airk to resist the tendency of the lining to cling to the plunger block. The mechanism for accomplishing this is as follows: The plunger block 9 is formed with a central bore 68 extending from the top nearly to the .i

bottom7 and when near the bottom, it is preferably branched having a plurality of outlets 69 through the bottom. Leading to the passage 68 through the block isa pipe 70 which may be a liexible hose connected by a suitable nipple with the entrance to the passage 68, the other end of the .hose 70 being connected with an outlet port 71 in a valve 72. The valve 79. is formed with an inlet port 7 3 into which a pipe 7 l leads from a suitable compression-pump or other source of supply of compresed air. The valve 72 is formed with a chamber 7 5 into which the inlet port 73 leads and is formed with a smaller chamber 76 connecting with the chamber and from which the outlet port 71 leads. A valve stem 77 reciprocates through a passage in the valve 72 and is formed with a conical head 78 which, when in its seated position, closes the passage :trom the inlet port 7 3 to the outlet port 71 and which in its open position allows free passage from the inlet port 73 lto the outlet port 71. The forward end of the valve stem 77 .is connected with a bell-crank rocking lever 7 9 pivoted at 80. Projecting from the shaft 26 1s a pin 81 which, at a certain point in the rotation of the shaft 26, engages one arm of the rocking lever 79, turning the rocking lever on its ulcrum, and thereby moving the valve stem 77 in a direction to open the valve and admit the compressed air through the port 71 and tube 70, thence through the plunger block 9. The pin 81 is so placed on the shaft 26 that the opening of the valve will take place when the plunger block is in its lowermost position in the carton, and the dwell of this pin on the arm 79 will continue long enough to keep the valve open until the plunger block has withdrawn from the carton.

In order to guide the carton into proper position upon the belt to be engaged by the reciprocating bar 17, guide rails 82 are provided above' the belt, and in order to guide the carton in its passage after the lining has Abeen inserted, another set of guide rails 83 are provided.

While as already stated, in the illustration of the invention shown the boxes are represented by what are termed cartons, the invention is not limited in scope, to the use of the machine for filling receptacles or containers of that particular type but in the use of the word'box or boxes in the specilication and claims it is intended to include any form of receptacle or container with which the machine is adapted to be used.
